Những chiếc đồng hồ tuyệt vời đến từ Thụy Sỹ

What's interesting, however, is that the watch was reportedly, "provided by the Russian Space Agency to Astronaut Mastracchio prior to the Soyuz launch," meaning the watch has both provenance connected to NASA, the agency Mastracchio comes from, and ROSCOSMOS, the Russian Space Agency. The Speedmaster comes on an elastic EVA band that's fitted on endlinks designed specifically for the band. The metal bracelet that's affixed to the Speedmaster at the factory was removed and left on earth, and replaced with the elastic band. I took a look through NASA's image archives to see if it was possible to spot the watch being worn by Mastracchio on any of the three spacewalks he performed during Expedition 38/39, but it is not visible. The watch was most likely flown with his personal effects, as Mastracchio is often seen wearing his Omega X-33 aboard the ISS.

The first spacewalk Mastracchio took part in was performed with the objective of repairing the failed loop A pump module on the starboard 1 (S1) Truss of the ISS. It lasted 5 hours 28 minutes. Together, Mastracchio and fellow NASA astronaut Michael Hopkins removed the pump and disconnected four ammonia lines before heading back in. The second spacewalk saw the same team replace the failed pump with a new one and reconnect the ammonia lines. This EVA lasted 8 hours and 7 minutes. Hopkins was attached to the Space Station Remote Manipulator System, also known as Canadarm2, and replaced the pump. Shortly after the two astronauts reconnected the ammonia lines, ammonia was once again flowing through the new pump.
